Quantifying Fluvial Sediment Transport by Anchor Ice

Abstract

Our long-term goal is to understand how anchor ice rafting acts a sediment transport and dispersal agent. Ice rafting is the transport of rock (of all sizes) by floating ice. Sediment is ice rafted by river, lake and sea ice that forms annually. Anchor ice is a type of ice that forms on the beds of rivers, lakes and seas. When anchor ice is released from the bed, it carries entrained sediment to the surface. This entrained sediment may be widely dispersed as the floating anchor ice drifts under the influence of wind and currents.
